I started my job a year ago and finished my first project recently. I am not a native English speaker, and I am always scared of public speaking. But my manager asked me to make a presentation in a conference.There will be hundreds of audience, which makes me so scard. I am really not comfortable doing it and I am so anxious. (Even though when I think of it, my heart beats so fast.) Is it okay to talk to my manager that I am not comfortable doing it because I am not confident enough and still lack of experience?
Would my manager be mad to me? When he mentioned me the presentation for the first time, I didn't think it was a big deal. But as the time approach, I got more anxious and had a hard time focus on work.
Please give me some suggestions.
